In the equation y=mx, how do you find m on a graph?

m is the slope of the equation y=mx+b. TO find the slope you look at the y intercept of the graph, b, and from that point find how much up/down and to the right/left you need to go. For example from point 0, 4, the y intercept, to another point on the graph (any point on the line would work) 2, 8 , I need to go up 4 units and to the right 2 units. The slope is 4/2 or just 2.'

If this is too confusing just find two points on the line in a graph and folow this equation: y2-y1 / x2-x1

where y2 is the y value of the second point, y1 is the y value of the first point, x1 is the x value of the first point and x2 is the value of x in the second point

Step-by-step explanation:

In the equation y=mx+b, m is the slope. The formula for slope is , so to solve find any two points on the graph and plug them into the formula. You could also count the difference, remember that slope is the change in y over the change in x. For example, if y increases by 3 units and x increases by 2 units then the slope is 3/2.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
